Hand auger drilling is executed by the GSMB field team using a manually operated enclosed-flight Spiral Auger (SP / SOS) system from Dormer Engineering in Queensland, Australia. Drilling proceeds to the water table, which is intersected at an average depth, for this dataset, of 1.5m from surface.

The first 0.5m advance is withdrawn and the contents of the auger removed onto a sheet and set aside for bagging. The subsequent samples are taken in the same manner at 1m intervals or until the hole is abandoned at the water table.

The whole sample is retained.

All drilling is completed above the water table.

Drilling and sampling activities are supervised by a suitably qualified GSMB geologist who is present at all times. All drill samples are geologically logged by the geologist at the drill site.

Each sample is bagged at site and transferred to the GSMB laboratory. Samples are dried and weighed prior to analysis.   

All samples are dried and weighed.  A riffle-split sub sample is then wet screened to determine slimes (-63 µm) and oversize material (+1mm).  Approximately 100g of the resultant sand sample is then oven-dried and passed over a Franz Isodynamic Magnetic Separator to produce magnetic (M) and non-magnetic (NM) fractions. The NM fraction is then subjected to heavy liquid separation (HLS) using Lithium heteropolytungstate (LST) with a density of 2.82g/ml.

All fractions are weighed and reported as a percentage of the in-ground total sample weight.

Grain counting of heavy minerals is completed by mineralogist and mineral assemblage data is then reported as a percentage of the HM fraction.

All samples are generated by hand auger drilling utilising 75mm diameter enclosed-flight spiral auger.  Drill holes are oriented vertically by eye.  

The GSMB's trained geologists supervise drilling on a 1 team 1 geologist basis and are responsible for monitoring all aspects of the drilling and sampling process.

No relationship is believed to exist between grade and sample recovery. The moisture content and absence of hydraulic inflow above the water table results in a sample size that is well within the expected size range.

Qualitative logs of geological characteristics are collected in the field to allow a comprehensive geological interpretation to be carried out. Drill holes are characterised by their location within the beach-barrier sequence to assist with domaining each sequence unit in subsequent resource estimations.

Logging of sand samples in the field is qualitative and includes description of sand colour, sorting and angularity. Estimates of black HM and garnet are recorded. A comments field is employed to allow further description of the location or sand sample.

All drill holes are logged in full and all samples are assayed.

All samples comprise unconsolidated sand.

Samples are taken in their entirety. Drill samples are oven-dried and split for analysis.

Sample preparation is recorded on a standard flow sheet and detailed QA/QC is undertaken on all samples. Sample preparation techniques and QA/QC protocols are appropriate for the magnetic separation and heavy mineral determinations.   

Samples are taken in their entirety. Laboratory duplicates are generated for precision analysis at the sample splitting stage. Results indicate a high level of precision is achieved. 

The sample size is considered adequate for a medium-grained sand.

 None used.

Quality assurance is maintained by laboratory duplicate and standard sample assaying procedure. Standard samples are provided by Placer Consulting Pty Ltd and are submitted blind to the laboratory. As a total sample is generated by the drilling, a field duplicate is not generated. A laboratory duplicate is created at the sample splitting stage.

Standards and duplicates are submitted at a frequency of 1:20 samples. They are subjected to the complete sample preparation and assaying process.

Analysis of sample duplicates is undertaken by standard geostatistical methodologies (Scatter, Pair Difference and QQ Plots) to test for bias and to ensure that sample splitting is representative.  Standards determine assay accuracy performance, monitored on control charts, where failure (beyond 3SD from the mean) triggers re-assay of the affected batch.

A high level of accuracy and precision are displayed in geostatistical analyses to date.

Significant intersections are customary from hand auger and sonic core drilling at the Eastern Minerals Project. Results in excess of 20% THM are common and in some cases, substantially higher concentrations are intersected. Placer Consulting considers this to be reasonable and consistent with beach, berm and foredune accumulations in a highly-mineralised region.  No audit analyses have been completed on these exploration results.

Twinned holes are drilled across a geographically-dispersed area to determine short-range geological and assay field variability.  Twin drilling is applied at a frequency of 1:25 drill holes.

Geostatistical analysis of twin drilling data awaits the return of all assay results.

Field logging data, photo's and maps are generated in the field by the GSMB geologist and provided to CMET staff in excel spreadsheet, pdf document and jpeg files. These data are stored in the master database at the Colombo office and on a secured cloud-storage facility that is accessible by invitation.

Assay data adjustments are made to convert laboratory collected weights to assay field percentages and to account for moisture.

The Kandawala Sri Lanka Grid is used to locate the drill collars.

Elevations are not recorded for these exploration results.

No mineral resource or ore reserve is considered in this report.

Samples are not composited. 

There is no apparent bias arising from the orientation of the drill holes with respect to the strike and dip of the deposit.

All samples are numbered, with sample splits, residues and HM sinks stored securely at the GSMB pending completion of the programme. Samples will be transferred for secured storage at CMET property upon completion.

The Competent Person completed an audit of the GSMB laboratory. Personnel, equipment and procedures represent best practice and no recommended improvements were forwarded. Data are monitored by CMET staff and reviewed by the CP as they are returned.
